US 78 begins at interchange withI-57/US 67at exit 102 where the roadway continues asAR 226west towardSwifton.The route goes through towns ofCash,Jonesboro,Lake City,Black Oak,Monette,Manila,Blytheville,Marion,andWest Memphisbefore crossing on theMemphis & Arkansas Bridgeover theMississippi Riverto enterTennesseeinMemphis.
Tennessee
editThis section needs to beupdated.(January 2024) |
US 78 enters Tennessee along Interstate 55 from Arkansas and shortly after diverges from I-55 onto E.H. Crump Boulevard. It is concurrent with US 61, US 64, US 70, US 79 and SR 1 until Third Street/B.B. King Boulevard. US 61 turns south onto SR 14 (Third Street) at this intersection. US 64, US 70, US 79 and SR 1 turn north onto SR 4 (Danny Thomas Boulevard), while southbound SR 4 becomes concurrent with US 78 and continues along E.H. Crump Boulevard. Around I-240, the road changes names to Lamar Avenue and continues southeastwardly to the Mississippi state line.[1]
Before the extension of this roadway into Arkansas, US 78 ran along MLK Avenue (formerly Linden Street) and Somerville Street until E. H. Crump Boulevard, turning onto Lamar Avenue. This former portion of US 78 was overlapped in its entirety byState Route 278(SR 278).
In Memphis, US 78 is historically known as Pigeon Roost Road, and some aborted sections of the highway in Mississippi also claim that name as well as Lamar Avenue.
Mississippi
editUS 78 is afreewayfor its entire length in Mississippi. The section from its intersection withInterstate 269inByhalia, Mississippito the Alabama state line is concurrent withInterstate 22.The highway runs across the northeastern rural part of the state, connecting several population centers. Mississippi's portion of US 78 is defined in Mississippi Code Annotated § 65-3-3. The old routing of US 78 through the state is signed asMS 178.
Alabama
editUS 78 is a major east–west U.S. highway across the central part ofAlabama.It is internally designatedState Route 4(SR 4) by theAlabama Department of Transportation,though the only section of State Route 4 that is signed is along portions mainly west of Jasper. The section from the Mississippi state line to nearGraysvilleis concurrent withInterstate 22;from Graysville south toBirmingham,US 78 takes its original routing. East of Birmingham to the Georgia state line, US 78 has been replaced as a major through-route byInterstate 20.The two routes roughly parallel each other, with junctions atLeedsandPell City.[2]
West of Jasper, old US 78 is signed as AL 118 to Guin, and the segment from Guin northward to I-22 at Hamilton is signed as US 43/US 278.
Georgia
editUS 78 enters Georgia inHaralson County,passing through the downtowns ofTallapoosaandBremen.It then proceeds throughCarroll CountyandDouglas County.In Douglasville, located in Douglas County, US 78 runs through the downtown, historical part of the city. It is the original thoroughfare for these Georgia counties.
The route then continues eastward throughCobbandFultoncounties intoAtlanta.After crossingPeachtree Street,where US 78 marks a boundary betweendowntownandMidtown,US 78 is largely conterminous withPonce de Leon Avenue.As it proceeds due east, this section of the route passesPonce City Marketand crosses theEastside Trailof theBeltLinebefore skirting a number ofFrederick Law Olmsted-designed parks in theDruid Hills Historic Districtat the eastern edge of the city.
After enteringDecaturinDeKalb County,US 78 departs from Ponce de Leon Avenue to head northeast. South of the site ofNorth DeKalb Mall,another short freeway portion begins — leading from just inside the eastern rim ofInterstate 285(the Perimeter) to thesuburbsofClarkston,Tucker,Stone Mountain,andSnellville.This portion is named theStone Mountain Freeway,and provides an excellent view ofStone Mountainfor eastbound motorists.
The route then proceeds east acrossGwinnett,Walton,andOconeecounties. In Oconee County, US 78 leaves Moina Michael Highway at theSR 316interchange, turning right and running concurrent with SR 316/US 29.(From this point, Moina Michael Highway is signed asUS 78 Business,which follows the original route of US 78 through Athens, Ga.) At the terminal eastern interchange of SR 316 both US 78 and US 29 turn right and join withSR 10 Loop,a mostly interstate-grade bypass that ringsAthens-Clarke County.US 78 exits the bypass and turns right at the Le xing ton Road interchange. From there US 78 passes throughOglethorpe,Wilkes,McDuffieandColumbiaCounties intoAugustaand then onto one of the twin bridges across theSavannah Riverinto South Carolina.[3]
South Carolina
editUS 78 provides the most direct route between Augusta and Charleston, through theSouth Carolina Lowcountry.CrossingSavannah Riverinto the state, it goes northeast intoAikenbefore going southeasterly through the cities and towns ofWilliston,Blackville,Denmark,Bamberg,Branchville,andSt. George.East ofDorchester,it parallelsInterstate 26into downtown Charleston, where it ends.[4]
History
editThis sectionneeds expansion.You can help byadding to it.(October 2014) |
In western Alabama, the historical name of US 78 isBankhead Highway.It is also known by this name in portions of Georgia, including Atlanta, and theBankheadneighborhood takes its name from that stretch of road. Also, the old section of US 78 (nowMS 178) that travels through downtownNew Albany, Mississippi,is namedBankhead Street.[citation needed]
Throughout the 2000s, US 78 has been gradually upgraded into a four-lane freeway in Mississippi and Alabama and signed asI-22.US 78 is concurrent with I-22 fromByhalia, Mississippito just outside ofBirmingham, Alabama,only branching off just outside ofGraysville, Alabamawith I-22 traveling about 11 miles (18 km) eastward to its terminus atI-65.[5]
On October 25, 2023, the Arkansas Highway Commission voted unanimously to extend the US 78 designation intoNortheast Arkansas.According to theArkansas Department of Transportation(ARDOT), the US 78 designation would be extended along several other routes from its current western terminus inMemphis, Tennesseeacross theMemphis & Arkansas Bridgeto a new western terminus nearCash, ArkansasatUS 67(Future I-57). The route would be cosigned along portions ofUS 64,US 70,US 79,I-55,US 61,I-40,Arkansas Highway 18(AR 18),AR 18S,I-555,US 49,US 63,andAR 226.This extension of the US 78 route designation was seen as a way to boost economic growth in the region by assigning a single route number for travelers to follow.[6][7]The extension was approved by AASHTO in November 2023.[1]
Future
editUS 78 and SR 4 inMemphis, Tennesseeis currently being upgraded between theMississippistate line andSR 176,a distance of about 5.1 miles (8.2 km). The route, Lamar Avenue, sees heavy freight traffic and has "crippling congestion." The work includes expanding the road from four to six lanes, adding three new interchanges, and upgrading additional ones. The work is being done in three segments with the first one starting in 2018.[8]
